I wrote this article a month or two ago, thought people here might be interested. Drexler-style nanotech research appears to be effectively dead at the moment.

Oh, and Yudkowsky responded to the article with characteristic obliviousness:

I broadly endorse this reply and have mostly shifted to trying to talk about "covalently bonded" bacteria, since using the term "diamondoid" (tightly covalently bonded CHON) causes people to panic about the lack of currently known mechanosynthesis pathways for tetrahedral carbon lattices.
